NEW YORK (AP) - A very confident adolescent boy stopped skating around the Rockefeller Center rink to ask Gretchen Bleiler something.

"What do you do?" he wanted to know.

She gamely turned the question around on him - learning he plays football and baseball, among other sports - before revealing that she's a snowboarder.

Bleiler and other U.S. Winter Olympians descended on the New York landmark Wednesday to celebrate a milestone moment: 100 days until the Vancouver Games. It was a chance to show off what they do as they make the final preparations for their sports' biggest stage.

Jeret "Speedy" Peterson, a 2006 Olympian in aerial skiing, drew a crowd with his high-flying tricks on a trampoline, bouncing and flipping on a pair of skis. Sarah Hughes, the 2002 figure skating gold medalist, took to the rink with a group of New York schoolchildren, who shrieked with delight as they tried to stay upright on their skates.

"Especially being down here with all the other sports and the media that comes in, it's definitely like, 'OK, now it's really close,'" said biathlete Lowell Bailey.

A hundred days can feel like a very short time to people who operate on a four-year plan. Ever since the U.S. relay team surged to a strong ninth-place finish at the Turin Games, Bailey has been consumed but what it will take to win a medal.
